This book was released on 2022-05-24 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although locusts are a type of grasshopper, they differ physiologically and in their behaviour. When environmental conditions allow, locusts multiply rapidly so that billions of them can aggregate and migrate vast distances devouring every growing green thing in their path. Plagues of locusts have occured for a long time and are even referenced in the Old Testament of the Bible. The magnitude of damage and crop loss that they can cause is enormous and beyond imagination. They have been the cause of starvation across continents in the past. The desert locust, Schistocerca gregaria (Forskål) is the most widespread and destructive of all locust species. When they invade they can cover about 30 million square kilometres and can include all or parts of 64 countries in the northwest and east of Africa, the Arabian Peninsula and central Asia, including Afghanistan, India, the Islamic Republic of Iran and Pakistan, among others.

Book excerpt: Migrant insect pests represent a constant threat to crops and to health in many parts of the world. In Africa alone, over $100 million is spent annually on the control of a half dozen species of locust. One of the key problems in combating migrant pests is that the insect can disappear for months at a time and reappear with catastrophic effect. With the aid of aircraft and radar, it has been possible to map the movements of migrant pests. The research in this book, carried out on an international scale, has shown that migrant pests can travel longer distances than previously suspected and that their movements are related to the dynamics of the winds and weather systems. These findings throw new light on the flight behavior of the insects as well as on the ecological and evolutionary aspects of flight migration and suggest new options for controlling pests, especially locusts and grasshoppers. In surveying the achievements in this area, the author provides the biologist with an introduction to the relevant aspects of meteorology.
